I agree we need the framework deal before the end of March. I also believe that it must be concrete and specific. It must meet the terms set forth by the IAEA and UN Security Council and must contain a robust verification mechanism. Otherwise, it will be clear that Iran has not made the fundamental commitments that are required to bring it into compliance with the IAEA's and UN Security Council's requirements.
I share concerns that political expediency may be pushing things toward a vague and relatively hollow arrangement. As I've stated before, without a credible framework deal, Congress should act. If Iran was not willing to meet its obligations after two prior extensions of deadline, there's little reason to believe Iran would suddenly change course over the next three months to reach a credible agreement. Moreover, the remaining three months were supposed to be about finalizing details, preparing the annexes, etc., to transform the framework agreement spelling out the major terms into a final agreement.
A non-substantive framework agreement won't mask the absence of agreement on the core issues, even as some might try to package it as a breakthrough. Without such agreement, the June deadline would be hit, and then the P5+1 would then be confronted with the choice of granting another extension with the hope that Iran will become flexible or reaching the firm conclusion that Iran is not prepared or willing to meet its international obligations. Moreover, the P5+1 would probably face a lot of pressure to grant the extension, at a minimum to sustain a narrative that progress is being made, even as fundamental issues remain unresolved. Therefore, I favor Congress's increasing U.S. sanctions against Iran, and adopting other measures aimed at undercutting its nuclear activities, if a credible framework agreement is not in place by the end of this month.
